Research Topics

In this paper, we discuss the balance sheet mechanics of the Swedish government. We examine spending, government bond purchases, and tax payments. As long as the Swedish central bank, which is created through Swedish laws, supports the Swedish central government, it cannot run out of money. The Swedish government therefore plays a large role in the Swedish economy. It can and should target full employment and price stability, bringing to bear its fiscal power.

Fractional reserve regimes generate fragile banking, and full reserve regimes (e.g., narrow banking) remove fragility at the cost of suppressing the role of banks as lenders. A Central Bank Digital Currency (CBDC) could provide safe money, but at the cost of potentially disrupting bank lending. Our aim is to avoid this potential disruption. Building on the recent literature on CBDCs, in this study we propose what we call the “CBDC next-level model,” whereby the central bank creates money by lending to banks, and banks on-lend the proceeds to the economy. The proposed model would allow for deposits to be taken off the balance sheet of banks and into the balance sheet of the central bank, thereby removing significant risk from the banking system without adversely impacting banks’ basic business. Once CBDC is injected in the system, irrespective of however it is used, wherever it accumulates, and whoever holds and uses it, it will always represent central bank equity, and no losses or defaults by individual banks or borrowers can ever dent it or weaken the central bank’s capital position or hurt depositors. Yet, individual borrowers and banks would still be required to honor their debt in full, lest they would be bound to exit the market or even be forced into bankruptcy. The CBDC next-level model solution would eliminate the threat of bank runs and system collapse and induce a degree of financial stability (“super-stability”) that would be unparalleled by any existing banking system.

A Stock-flow Consistent Model

This paper presents a stock-flow consistent model+ of full-reserve banking. It is found that in a steady state, full-reserve banking can accommodate a zero-growth economy and provide both full employment and zero inflation. Furthermore, a money creation experiment is conducted with the model. An increase in central bank reserves translates into a two-thirds increase in demand deposits. Money creation through government spending leads to a temporary increase in real GDP and inflation. Surprisingly, it also leads to a permanent reduction in consolidated government debt. The claims that full-reserve banking would precipitate a credit crunch or excessively volatile interest rates are found to be baseless.
